To a/ZZ whom t may concerm. Y

Be it known-'that-I, JAMES G. DELANEY, a citizen of the United States,and a resident of New York city, borough of Manhattan, in the county ofNew York and State of New York, have invented a new and ImprovedHoisting and Conveying Device, of which the following f is a full,clear, and exact description.

My invention relates to improvements in hoisting and conveying devices,and is herein illustrated as applied to a cableway, although it isevident that it may be employed as well in connection with any otherform of tramway.

My invention comprises the novel features hereinafter described andparticularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view` of a cableway constructed in accordance with myinvention. Fig. 2 is a side elevation of engine-drums such as arerequiredv for operating such a cableway. Fig. 3 is a sectional sideelevation of the carriage, taken between the side plates or framesthereof, dotted lines H being added to indicate the position of thehoist-actuating rope. Figs. 4 and 5 are end and side elevations of amodified form ofcarriage. Fig. 6 is a top plan view of the blockcarrying the carriage-operating ropes at the tail end of the cableway.

A carriage C is provided with wheels l 2, adapted to runupon anysuitable form of trackway, said trackway, as shown, consisting of thesupporting-cableA. .A traction-rope B of the usual endless type isprovided,by means of which the carriage may be caused to .travel alongthe trackway as desired. At theheadsupport or tower the runs of thisrope pass, respectively, over the pulleys 3 and 4' and then p about adrum E of the engine, which is looselyT Y The carriage-frame is hereinfor simplicity shown as consisting of-two plates. Between these platesare journaled the wheels 1 and 2, which run upon the trackway andsupport the carriage, and the chain or hoisting pulley, sheave, or drum8, which should preferably be a pocket or a sprocket wheel, which isadapted to engage the hoisting-chain I. When the hoisting member 8 is ofthe pocket or sprocket form shown it constitutes a clutching hoistmember, which progressively clutches and releases the load-suspender Iwithin each cycle of movement, andy therefore enables the point ofsuspension of the fall to be maintained in a laterally constant positionwith respect to the vertical plane through the supporting-cable A.Journaled upon the carriage is a wheel 7 which is adapted to receiveasuiiicient number of wraps of a hoist-operating rope H so that powermaybe conveyed by the frictional grip of the ropes thereon to raise theload. This rope is an endless one, passing about the pulley 5 at thetail-support, one run passing over each of the pulleys 9 and 10 at thehead-support and then passing about the drum D at the engine. This drumis shown' as keyed to the shaft, although it may be provided with afriction-drive and a brake, if desired. It will be observed that inoperation the run of the hoist-operating rope H between the sheave 7 andone end of the trackway will perform the function of ahoisting-ropa'while the run'of the rope H between the shea-ve 7 and theother end of the trackway will perform the function of a slackpullingrope to prevent the sagging of the hoisting-run of the rope H during thelowering of the fall. Thus in Fig. 3 the run of rope v-H shown in dottedlines at the left Yof the i sheave 7 constitutes the hoisting-rope, infact, while the run of the rope H shown in dotted lines at the right of`thesheave 7 constitutes, vin fact, a slack-pulling rope, because1 inlowering the fall it, in fact, Outhauls thehoisting-rope, and thussupports it from sagging.

Power is communicated by any suitable mechanism from the sheave 7 tothechainwheel 8. The means herein shown consist of -the pinion 1l vandgear l2, secured to the respective shafts or so as to turn,respectively,

'A with sheavel 7 and chain-wheel 8, A chain IOO storage-drum 14: isprovided, which is geared toturn with the chain hoist-wheel 8 and takesin and pays out the chain approximately as the chain-wheel 8. With thetwo geared together by the gears 12 and 16, as shown, the

rate of actuating the chain will vary; but the variation in rate will beaccounted for in the loop which hangs between. Small guide-pulleys 13,placed one on each side of the chain close to the wheel 8,'take any sidepull and prevent the chain from being pulled 0E of the chain-wheel. Aclevis 15 may also be secured to the frame and one end of the chainattached thereto and a fall-block be suspended in the loop formedbetween said clevis and the chainwheel. This will increase the hoistingpower of the device over the direct attachment of the load to the end ofthe chain.

In Figs. 4L and 5 a modified form is shown, in which two chain hoist andchain storage wheels arel employed, one pair on each side of thecarriage, and the rope or driving wheel 7 is placed between thecarriage-frames. In this construction there are two hoisting-chains II', repectively pendent from the two parts 8 8 of the hoist on theload-carriage and connected together at the bottom by a yoke 20, whichis provided at thev middle with a loadsupporting hook 21. Thisconstruction has the advantage of maintaining the load attachment 21substantially in the vertical plane of the Wheels 1 2 even though thewinding of the suspenders I I' upon the hoist parts 8 8 should vary thedistance between them. Where the fall consists of only asingle suspenderI, there is no means of compensating for any sidewise variation from thevertical plane of the wheels; but where the fall consists of the twosuspenders II', yoked together, as in Fig. 4, it enables the two parts 88 of the hoist to be so constructe'd that any sidewise movement of onesuspender in the course of winding or unwinding can be compensated forby an inverse sidewise movement of the other suspender, so that theresultant may maintain the load-support 21 constantly in the samevertical plane.

In connection with the engine in Fig. 1 I have shown a means for takingup slack or applying tension to the operating-ropes.:

This consists in a wheel 16', which receives one of the wraps of therope passing about the engine-drum, said wheel being adjustable in anyconvenient Way toward and from the engine-drum. The means shown,although not the only means which may be used, consists in journalingthe wheel in a frame 17,

which is mounted to slide on guides and is controlled in position by thethreaded rod 18. At the tail end of the cableway another means 'r foradjusting tension on the ropes is shown. This consists in journaling thesheaves 5,about E which these ropes pass, in a block 6, which is 1clamped upon the main cable A. This block g has ears for the attachmentof ropes or chains by which it may be pulled back until the ropes aresuiiciently tightened.

It will be noted that by the use of'a chain hoist-wheel and a chainstorage-wheel theY pull of the load is always upon the same point anddoes not shift laterally of the direction of the cableway. Incableway-carriages containing a drum which is both a hoisting and astoring drum the position of the hoist-rope varies laterally withrespect to the plane which includes the supporting-cable and isperpendicular to the hoisting-drum axis. As the hoisting-rope variesfrom this plane it throws a side strain upon the drum, which as thecarriage is suspended tends to cause the hoisting-rope to run off theend of its drum. This tendency is suflicient to prevent the practicaloperation of devices of this character. The side strain has in suchcases been sufficient to` make a cable climb over iianges ofconsiderable depth.

By my invention the draft of the hoistingchain is kept at all times in adirect line beneath the supporting or trackway rope and there is no sidestrain tending to pull the chain off of its wheel. 'The avoidance ofside draft might be secured by having the chain coil upon itself; butthis would greatly vary the power of the hoist, which result wouldordinarily be very objectionable; By my construction the draft is alwayscentral and the power is constant. By using a chain of sufficient lengthit is possible to bring in loads from a great distance in either side ofthe line of the cableway, thus increasing its efficiency. To take theside strain necessary to swing the carriage into line with the strain insuch cases, the guide-rollers 13 are provided on each side of thechain.- These are not needed after the chain becomes strained, as thenthe carriage swings so that the draft is central.

While I have herein shown the storagewheel'as geared to the hoist-wheel,it is evident that it may be turned by a frictional connectiontherewith, in which case its speed may be varied by permitting slip, orit may be connected .directly with the wheel 7, over which thehoist-operating rope passes.'

I have only shown and described the use of a chain for hoistingpurposes, not that a rope may not be used, but because a chain lendsitself to use with a simple hoist mechanism of the character desiredbetter than a rope does. A grip-wheel or double hoist-.drums might,however, be used with a rope Vinstead of the pocket-wheel and chain.

Since various features of my inventionmay be employed, omitting others,and the parts or elements may be varied to a great extent, I do not wishto be understood as limiting myself to exclude such omissions orvariations.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- IOO IIO
